Lockout operation
Lockout operation combines the mechanical
tripping / opening of the recloser and the
interlocking to inhibit subsequent closing of
the recloser.
The lockout can also be operated when under
load.
For three-pole recloser, all three poles will be
operated simultaneously by the mechanical
link of all poles.
Open the recloser
1. Using a hot stick or suitable rod from the
ground, pull down the lockout handle
until it reaches the end (lower) position.
The recloser opens. By operating the
lockout mechanism, the recloser is
opened mechanically and locked in this
position.
The mechanical position indicator on the
bottom of the recloser switch unit shows
green.
The green OPEN LED on the protection
and control relay indicates the switch unit
has operated.
The switch action is completed.
As long as the lockout handle is pulled out, it
is not possible to close the recloser
electrically, whether locally or from a remote
location.
Closing the recloser electrically from the
controller
1. Using a hot stick or suitable rod from the
ground, push the lockout handle back in
completely.
2. Follow the control and protection relay
instructions to electrically close the
recloser.
The recloser closes.
After switching, confirm that the red
CLOSED LED on the control relay indicates
the switch position has been reached.
Confirm the green OPEN LED is off.
The switch action is complete.
The mechanical position indicator on the
bottom of the recloser switch unit shows
red.
Note: The lockout handle needs to be pushed
back completely. Otherwise, the interlocking
still prevents closing.
